orinner tubes; the provision of a metallic tread for preventing the wear of the outer casing and the skidding of the tires on Wet surfaces, and at the same time insuring resiliency to the tires; and means whereby the creeping of the tread on the tires may he prevented.

Other objects may appear in detailed description of my device as illustrated in the accompanying drawings in which:

Figure 1 is a segmental portion of a tire, partly broken away at the center lines; Fig; 2 is a cross section of the same; is a fragmentary view of the outer portion of the tread belt; Fig. 4- is a similar View of the inner portion thereof; and Fig. 5 is an. e largecl fragmentary section of the belt and plates, similarto Fig. 1.

Similar reference numerals indicate the same parts throughout the specifications and the several views of the drawings.

The outer casing 1 is very similar to the common types of such casings except that its outer periphery 2 is formed on a radius greater than the radius of the sides of the casing, and this portion is also slightly thinner than the sides in order to provide a greater resiliency to this part of the casing.

i provide a suitable belt 3 made of the same material and of about the same composition of the tire casing 1. On the outside of this belt I provide a plurality of tread plates 4, and on the inside of the belt an equal number of flat plates 5 having the downwardly extending ends 6 adapted to conform to the sides oil the casing 1 and hold the belt on the casing, the plates i and 5 being secured to the belt by the rivets 7. The heads of the rivets 7 are countersunk in the transverse grooves 8 of the plates 4 on the outside of the belt 3 and the inner ends are countersunk on the inner side of the flat platesfianil are slightly pointed and. adapted to sink into the tire casing 1 and prevent the creeping, either trai'isversely or longitude nally, of the belt on the tire.

also pro idedn'ith a plurality is 'es 5/ extending entirely so the traction, and

plates :3 are of it across i i to me the rec 5 on the bottom which, when the plates are in position on the belt 3 form air chambers between the plate and the belt and prevent the heating of the belt and the tire. The plate: -72 and 5 are so positioned with regard to e: ch other that the belt 3 is protected at all points loy a metallic covering, the interstices between the plates 5 on the inside of the belt 3 being on a radial line which would cut the plates 1t substantially near the center, so that in the event of a nail,

tacit or other sharp substance which would ordinarily serve to puncture the casing 1 entering one of the interstices between the outer :atl, plates i it would be prevented from c tering the casing l, and a puncture would o: averted. The interstices between in plates on both sides oi the belt 3 should he Wide enough to providea freedom of statement to the plates as the belt and tire retract in the running of a. vehicle and so that the adjacent plates will not contact and cause a rattling as the wheel revolves.

The belt 3 with its full equipment of plates s and 5 is adapted to be placed in position on the outer portion 2 of the tire casing 1 when the tire is deflated and when the latter is inflated the belt will be held securely in position by means of the outer ends of the inner plates and the inner ends of the rivets '7, as hereinbefore described.

Having thus described my invention, what Exclaim as nev and desire Letters Patent for is:

1, A pneumatic rehicle tire comprising an outer casing provided with a. flattened pe ripheral face and an armored tread com posed of an endless resilient belt provided with a plurality of closely spaceih inner and outer, transversely disposed metallic plates, said belt being adapted to seat on the liattoned peripheral face of said casing, said responding in width to and adapted to seat on said peripheral face, said tread comprising an endless non-metallic belt provided with a plurality ofclosely spaced, transversely disposed inner and outer metallic plates Whose length corresponds substantially to the Width of said belt, the inner plates being staggered with respect to the outer plates and commonly secured therewith to said belt, said outer plates having transverse recesses on their inner surface adjacent to said belt, and said inner plates being adapted to firmly hold said tread in position on said casin '3. A pneumatic vehicle tire including an outer casing provided with a flattened peripheral face and an endless armored tread corresponding in width to and adapted to seat on said peripheral face, said tread comprising a non-metallic belt, an outer set ot closely spaced, transversely disposed metallic plates provided with inner transverse recesses, an inner set of closely spaced, transversely disposed metallic plates, staggered With respect to said outer plates and adapted to hold said tread firmly in position on said casing, and common securing rivets for said outer and inner plates the inner ends of which are adapted to projectinto the peripheral face of said casing for preventing a transverse movement of said treadthereon.

4. In a device ()iT tlIQ character described, the eombination of an outer casinghaving the central and outer portion of its periphery formed on a larger radius and substantially thinner than the sides thereof; a resilient belt around the outer periphery of said casing; a plurality. of transverse metallic tread plates having transverse recesses on the inner sides thereot' mounted on the outer side of said belt; a plurality of transverse metallic inner plates having their ends bent downwardly ove' and in contact with said casing and on the inner sideot said belt: and rivets common to both said outer and inner plates for securing the same to said belt in pairs; the inner ends of said rivets being slightly pointed and adapted to sink into said casing for preventing the creeping of said belt thereon.
